I'd put a 36 TALAS on the Spot (2009) but if I got the RFX, I'd probably run the Vanilla. However, if the 2009 36 TALAS is better at dealing with small bumps than the older ones, I'd spring for that just for the adjustability.

Just my 2c in air, if I had to choose air for the RFX I'd go for a Wotan myself without all that bar crap, I like Magura's stuff, so Im a little biased and I've never gotten ove my first talas ride experience I just can't like that fork in the 36, I had a talas rlc125 and in its day it was a sweet fork but so much has improved since then!
